FLORA OF SOUTH AMERICA AND THE PACIFIC. 41 



celUs nudis, invol. squamis oblongis $ ex axillis longius 

 pedicellatis, pedicellis bracteolatis, invol. squamis ovatis ohtu- 

 sissimis laxis rufo-velutinis, floribus in ind. ? 5-6, achseniis 

 glabris, corolla rigida pappo pluriseriali. DC. — B. ochracea, 



)Spr,? — Maldonado. Tweedie Leaves 4-6 lines long, patent or 



reflexed. In our specimens the younger ones only are wholly 

 tomentose, in the older ones the upper side is more or less 

 bare, the under always densely velutino-tomentose, tlie invo- 

 hicre thickly so and ferruginous. Our plants are all male, 

 and the capitula, at first sight, resemble those of Artemisia 

 Absinthium ; the scales are short, oval, very obtuse, lax and 

 somewhat spreading. De CandoUe doubts if the male and 

 female plants he has described belong to the same species, 

 perhaps the following has been confounded with it.
